almost all (? probably all) "modern" nvidia cards (>= fx) will have 2
VGA-outputs, and they cost very little. (~70€, guess you can get one for

just use nvidia's "TwinView" to drive a xinerama-like dual-head screen
with hw-acceleration on both.

even if matrox has "dri" support, this is (to my experience) nothing you
can compare with nvidia's (and probably radeon's) acceleration.
with _wild_ numbers i'd say:
matrox-DRI : 3x
nvidia-GL : 50x (well, probably 10x or 20x)

well, there are mainboards with 2 AGP-slots (are there ?)
or you can use 1 AGP and 1 PCI card (like chris has mentioned, PCI is
not that fast with texture uploading)
i think you would have to use 2 X-servers on your machine and then run 2
instances of pd/gem
